The Industrial Raspberry Pi Forum

I’ve just received a new RevPi Connect+ (32GB) and have been trying to back up the installed image from my Windows 10 machine as described here:
https://revolution.kunbus.com/tutorials ... ng-images/

I was able to successfully run the RPIBoot and then the Win32 disk imager but the final result (which took over an hour to complete) was an image file of 29.1GB. I repeated the process wondering if I had made a mistake and got an identical result.

I have checked the disk usage on the machine itself via SSH and get the following:

```
pi@RevPi21499:~ $ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/root 29G 2.4G 25G 9% /
devtmpfs 459M 0 459M 0% /dev
tmpfs 464M 0 464M 0% /dev/shm
tmpfs 464M 6.2M 458M 2% /run
tmpfs 5.0M 4.0K 5.0M 1% /run/lock
tmpfs 464M 0 464M 0% /sys/fs/cgroup
/dev/mmcblk0p1 44M 22M 22M 50% /boot
tmpfs 93M 0 93M 0% /run/user/1000
```

The web interface says I have 24.98 free.

Hi sirockin, the image of the system is just a raw copy of the contents of the eMMC. So you cannot enhance this process at all but you may use some compression software afterwards to shrink the image file.

Thanks Dirk. So just to be clear, if I restore the Rev Pi from this image, the disk space utitlisation will be as before - 2.4GB?

Hi well yes. But the process of saving or restoring the image takses the whole space on the eMMC which is in your case 32Gb.
